'Eye bath' to thank for birds' quantum vision

摘要

Moveer, Schrodinger's catbirds may be the true quantum animals. A bath of cells in the back of a bird's eye could prolong a delicate quantum state that helps to explain how some birds navigate using Earth's magnetic field. It is thought that light reacts with receptors in the birds' eyes to produce two molecules with unpaired electrons, which are linked by a special state called entanglement.
